Florida Power & Light is committed to building the world's largest solar battery storage system, and announces plans for its vast Manatee Energy Storage Center.
The tool plans to build a 409 MW / 900 MWh battery to be operated by an existing FPL solar plant in Manatee County, Florida. It will start serving customers in 2021.
FPL says the battery system will be able to operate 329,000 homes for two hours. By comparison, the FPL notes that the battery system is equivalent to 100 million iPhone batteries, or 300 million AA batteries. The system will be used during periods of high demand.
Manatee Energy Storage Center will accelerate retirement of two natural gas plants at a nearby power plant. The FPL says the project will save customers over $ 1
The FPL has already announced a goal of installing 30 million solar panels by 2030, and the utility recently announced plans to build four new solar power plants this year. FPL President and CEO Eric Silagy said,
"This is a monumental landmark in realizing the full benefits of solar energy and another example of how the FPL is working hard to position Florida as the global gold standard for pure energy. perform our plan to install 30 million solar panels by 2030, we never seem to find innovative ways to give our customers the benefits of solar energy even when the sun is not shining. "
Batteries Get Big  The Manatee Energy Storage Center Battery System is expected to have four times the capacity of the world's largest battery system currently in operation, so FPL bills it as the world's largest solar powered battery. But it will get competition.  There are already plans to build a 495 MW battery store in Texas, which Bloomberg reported last month. That system would be paired with a similar 495 MW solar farm in Borden County, Texas. It will also come online in 2021.
The project will be developed by a unit of San Francisco-based Intersect Power LLC called IP Juno, but at this point little information seems to exist beyond the first reports.
Hawaiian Electric has just announced plans for six solar + storage projects that will provide nearly 1 GWh of storage space. None of the six projects on their own will be as large as the planned projects in Florida or Texas, but it still illustrates how the battery storage size increases rapidly. In this context, it appears that at the time FPL or IP Juno completes its projects, a larger project will be announced, if not already under construction.
